Specific embodiment
The present invention is illustrated below according to attached drawing illustrated embodiment.This time disclosed embodiment can consider in all sides
Face is to illustrate, without limitation.The scope of the present invention is not illustrated to be limited by following implementation, only by claims
Shown in range, and including having all deformations in the same meaning and scope of the claims with scope of the claims.
Preheating section, eventually cold section of spray box processing method of the present invention are illustrated combined with specific embodiments below.
Shown in referring to figs. 1 to Fig. 3, cold rolling vertical type continuous annealing unit and galvanizing unit annealing furnace preheating section spray box processing of the present invention
Method includes the following steps:
(1) material is selected, because the inherent strain of Yuanping City's plate is less than roll bending, in order to reduce stress deformation, therefore material selection is former
Plate, using laser cutting, drilling processes multiple nozzle plate materials, two outer panels 1 and back shroud 2 for material, using sharp
Light cutting stock precision is high, and can be very good to guarantee the degree of deformation of blanking, provides good elder generation for assembly and subsequent welding
Precondition sprays twice bending line in each nozzle plate material being cut into, why sprays bending in advance at pre- flanging position
Line is because former flat thin is easily deformed, it is difficult to control size, in order to guarantee the flanging compact dimensions precision of nozzle plate 3, roll over
When side according to bending line carry out flanging, formed nozzle plate 3, it is ensured that flanging molding when, control errors ± 0.5mm with
It is interior, guarantee in a large amount of flanging process, to provide the molding of high quality, the flanging angle of nozzle plate 3 uses angular mould
It is detected, reinforcing rib 8 is welded on each nozzle plate 3；
(2) in order to ensure assembly precision, multiple nozzle plates 3 is installed together to form multiple nozzles 4 using mounting plate 5, are adopted
The scale error of components can be cut down with the assembly that mounting plate 5 carries out spray box.Because there are differences in height for the size of nozzle 4, and
Back shroud 2 is plate.We have designed and produced mounting plate 5(according to the difference of height of nozzle 4 and have seen Fig. 4, Fig. 5 institute according to this configuration
Show).And sample is amplified on mounting plate 5, i.e., it is crossed on mounting plate 5 according to the size of spray box, marks spray box
Assembly center line, nozzle location line and outside printed line.In assembling nozzle plate 3 and outer panel 1, specific steps include:
A, mounting plate 5 is surveyed and is put down, make to be placed on 4, nozzle formed between each two neighboring nozzle plate 3 on mounting plate 5
The flatness set is≤2mm；
B, in order to guarantee the size of nozzle 4 and the spacing of two nozzles 4, the position setting between adjacent two pieces of nozzle plates 3 can
To control the control block 6 of 4 width of nozzle；
C, according to the requirement for height of nozzle 4, height adjusting block 7 is added respectively in the two sides for being close to control block 6, to adjust nozzle 4
Between existing ladder height it is poor；
D, the two sides of printed line increase for the block against outer panel 1 on the outside, prevent 1 positioning of outer panel or deformation；
(3) first time welding is carried out after assembling nozzle plate 3 and outer panel 1, welding process pushes down nozzle plate 3 using counterweight,
And outer panel 1 is fixed on mounting plate 5, because spray box height is very low, only 350mm height, so in nozzle plate 3 and outer
Side plate 1 first welds the weld joint on inner side between outer panel 1 and each nozzle plate 3 after having assembled, because spray box is symmetrical structure,
The weld seam on both sides is symmetrical, if made by the way of directly welding in production, will lead to spray box plane after molding can not
Reach requirement, and the flatness of nozzle 4 is overproof, therefore used in welding and be symmetrically welded progress, and control welding direction,
It can be very good to guarantee welding quality；
(4) by the assembly of back shroud 2 rear end position on outer panel 1；
(5) outer panel 1 and nozzle plate 3 are welded again, because spray box is longer, length reaches 10m or more, and two sides are shunk in order to prevent
Inconsistent, using being symmetrically welded, i.e., spray box two sides carry out welding using two workers simultaneously, and from it is intermediate forward, rear both ends weld
The mode of connecing carries out, until being welded into preheating spray box.
Spray box is pushed down by progress using clump weight or fashioned iron in the whole welding process.
By above-mentioned steps, cold rolling vertical type continuous annealing unit and galvanizing unit annealing furnace preheating spray box is made.
With reference to shown in Fig. 6 and Fig. 7, cold rolling vertical type continuous annealing unit and galvanizing unit annealing furnace of the present invention cold section of spray box processing eventually
Method, most of step is identical as the step of preheating spray box processing method described in above-mentioned Fig. 1 to Fig. 3, and something in common is no longer superfluous
State, be a difference in that: spacing of the present invention eventually between the nozzle of cold section of spray box is bigger than the spacing between preheating section nozzle, weld seam
Length is longer.
Cold rolling vertical type continuous annealing unit and galvanizing unit annealing furnace preheating section spray box processing method of the present invention, cold section of spray box adds eventually
Work method is designed by above-mentioned procedure of processing, due to cold rolling vertical type continuous annealing unit and galvanizing unit annealing furnace preheating section spray box and end
The length of cold section of spray box is long, the accuracy of manufacture require it is high, and all using thin plate box structure, without any type steel support, because
This present invention uses laser blanking, molding in the blanking of components, to the side such as dimension control, welding procedure, assembly technology
Face is improved, and not only can control the precision and welding deformation of components, but also reduces the scale error of components, it is ensured that batch
Measure the equipment precision under working condition.Processing method repeatability is strong, while ensuring quality, can preferably improve system
Make speed.
